i am truly sorry if im wrong.
- We know, sum of all angles of a triangle is 180°.
- Therefore, by the problem
72 + 64 + (4x+20) = 180
or, 156 + 4x = 180
or, 4x = 180 - 156
or, 4x = 24
or, x = 24 ÷ 4 = 6

The 3rd term is

Step-by-step explanation:
From the given information, the first term of the sequence is

The common ratio of the sequence is

The explicit formula for a geometric sequence is :

To find the third term, we put n=3 to get:

This simplifies to:

Answer:
Step-by-step explanation:
nfant mortality is the death of an infant before his or her first birthday. The infant mortality rate is the number of infant deaths for every 1,000 live births. ... In 2019, the infant mortality rate in the United States was 5.6 deaths per 1,000 live births.
Divide the perimeter by 3 to get 8 then use the equation for the area of a triangle (a= BH1/2) and your answer is 32
